One nice sunny day, a spotted and very diligent dog was working in his beautiful and very neat little garden. He was pulling a tough weed when he looked up and said, "What in the world!?", because he had seen his neighbor fox's, yard. It was all overgrown with weeds and vines. The worst part was it was growing over the fence into dog's yard. "That annoying fox," Sighed dog. "He's so lazy he won't even take care of his own yard. I've gotta do something." So dog thought and thought until finally he had an idea. "First," He thought aloud, "I'll let my garden start overgrowing. then I'll help fox clean his yard and show him how affected I am by his laziness." So that's what he did. Sure enough, fox complained to dog. "Dog your yard is bothering me. clean it up please." "Whoa, whoa, whoa fox," Said dog. "You're saying that I have to clean my yard when you don't ever have to?" "Well," Said fox looking a little embarrassed, "I just don't like work, but now I see that the sooner you do your work the less of it you'll have to do. c'mon, I'll help you clean your yard." "Thanks," Said dog. And off they went. They both realized that is best to not wait till later. 
It is best to do today's work today.
